Application lcsl February 511, 1822. Serial No. 535,887.

To all whom if muy conf-em:

Be it known that l. Mrcrmsl. A. Keim. u citizen of the .I uitcd* Stutcs. residing at Burkburnett. .in the county of 'ichitu undy Stute of Texas. huvevinvcntwl ccrtuin new and useful improvements in lumps. ot' which thc following is u specification.

My invention rchites t0 mmps und more particularly to working mrrcls. packing .10 and packing chambers: ond the object is to provide pumps with packing und pui-kin. chambers therefor in combination witlil workin barrels in which uniny ports. such as poc ting cups. und other cusilv worn i5 parts, nre eliminutcd. und to provide pack ing chambers in which thc packing will hc automatically maintained. und to iroride packing and packing chambers nmll plungeis which will notv be effected by sund or dirt and other minding!l or cutting particles and also eliminate thc frcqucnt pulling,r of rods to chungccups. and to provide pumps which will be highly cllicicnt in pumping` oil and other liquids. One of the advantages of the improved pump is that thc'cutting of the oilwill be largely prevculed. Another advantage is that the pressure of the liquid usually attendant upon thc pulling of the plungers with their cups is ircvented und b v lifting of such cups is prevented. Other objects und advantages will be fully explained in the following description und the invention will be more particularly pointed out in the 95 claim. l

Reference is had to the zmiompunvmgv drawings which form n part of this application.

Fig. 1 is a vertical section of a. portion of acki chamber and the packing therein. ig. 2 is abroken vertical section, illustrating the continuation of the pum ingbarrel and casing shown in Fig. 1. dg. 3 is a broken vertical section. onta smaller scale, of the casing shown ,if

therein!- Similar characters of reference are used to indicate the same parts throughout the Fig. 2 and showing u check valve A swaged collar i is screwed on the upper end of the packing chamber l and this reducer -l is connected to the casing 1 by a collur. The working barrel operntes throu h the packing chamber and through the paciing T therein. A' packing supporting ring 1s mounted in the lower end of the pacte mp; chamber und supported therein by the su-a 'd end 9 of the packingv chamber. The per ing 7 is placed in the chamber 1 about the working borrel and c packing-com pression 'ring l() is placed on top of the pecking 7. Any pressure by liquid on the ring 10 will be transmitted to the aching 7. The pressure on the packing- 7 will thus be automatically maintained. A cup-shaped cavity 11 is formed in the upper end of the ring lu about the bui-rel to aid in 'forming a seal about the borrel by maintaining liquid about the barrel during operation. The upproximntelv funnel shaped cavity 11 cooperates with the tapered member 12 of thc workin barrel to malte the projection ot the ivm-ring barrel through the packing 'eusily accomplished. The pressure on the packing 7 will expand the packing against the barrel 6 und against, the well of the clmmher 1. The lower end 12 of the working borrel 6 is reduced to molte the barrel easily opcrutive through the packing cham ber. The lower end of the working barrel is connected to the main barrci by a` screw joint 13 and a vulve seat. 14 is formed in the upper end of the section 15 of the pump barrel. A check valve 16 is provided for the pump barrel und is adapted to engage the sent 14 on the upstroke of the barrel. The working barrel section l5 is provided with openings 17 therethrough for relieving the pressure of theliquid in the casing 2 and in the reducer 4 about the barrel 6. When the openings 17 pnss above the ring 10, the liquid in the casing 2 und the reducer 4 will pass down inside the member 15 and thus relieve the pressure; on the barrel. A. coupling 18 connects the intake pipe 19 with the casingr 2. A valve 20 and coge 21 therefor are provided and a pipe 22 forms a communication between the intake pipe 19 and the casing 2 through the valve seat of valve 20. In operation the liquid passes up throuih the .intake pipe 19, thence through t e pi pe 22 und ast the valve 20 into the casing' 2. The wor inp; barrel 6 with reduced end 12 takes the liquid from the casing Ve- .rous changes in the sizes, construction and arrangement of the several parts may be barrel insaid casing operating throughsaid marde without departing from my invention. paeki end having a tapered vnlved sec- 16 at Ieaim, is, tion etachablv connected thereto, said A pump having u casing in sections, an valved section'havlng an integral valve seat -s enlarged licking chamber having a swaged therein and having perforations below said .lower en for connection with said veasing, seat for relieving pressure on said working pacldng'in said chamber, a ring supporting -harrel' when said barrel passes above said 2o lsaid packing and resting on the swaged porpacking, and a. valve adopted to engage said ton 'of said chamber, a, ring compressor for seat.
